AirA robotics startup that scans and inspects wind turbines so that humans don’t have to, received $38.9 million in new funding this month from dozens of investors. undisclosed, TechCrunch is aware of.
Wind turbines generate clean energy, but their towers tend to oil leak, which can corrode blades, increase wind resistance, and contaminate the ground below. Aerones’ remote-controlled robots clean the towers and propellers by spraying them with liquid detergent, while hoppers below the propeller collect clogged liquid for reuse. The robots also inspect the turbine system with cameras and ultrasonic scanner.
Aerones’ website says the company has cleaned more than 5,000 turbines to date across 19 countries. For context, there’s more 72,000 wind turbines only in the US. In 2021, turbine generates about 9% of all electricity in the states.
Backed by Y Combinator and from Latvia, Aerones aims to raise at least $2.5 million more, according to a submit with the Securities and Exchange Commission. The startup did not immediately respond to a request for more details about the round.
In April, Aerones stuffed in $9 million in seed funding from France’s Future Positive Capital and Estonia-based Change Ventures. At the time, co-founder Dainis Kruze said the company was “rapidly scaling up” and had worked with nine of the 10 biggest companies in the industry, including GE.
